Quality Control

Our 3-Amino-5-Hydroxy-4-Phenylazopyrazole is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) detailing specific test results are provided with every shipment to guarantee full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
